DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 696,333, dated March 25, 1902. Application inea Tammy 11, 1902. serai No. 89,264. (No model.)

To @ZZ who-m, it may concern: y

Be it known that I, HENRY HENDRICKS, a citizen of the United States, and a resident of Kinbrae, in the county of Nobles and Statel of Minnesota,'have invented new and useful Improvements in Draft-Equalizers, of which the following is a full, clear, and exact description.

My invention relates to improvements in draft-equalizers; and the object that I have in View is the provision of an improved draft device adapted to even up the draft exerted by a team of ve horses, one of which may walk in the furrow,while four horses may walk in the stubble if the equalizer is employed on a plow, although it is evident that the structure may-be used on vehicles or any other apparatus where the power of such a team is desired or required.

With these ends in view the invention consists in the construction, combination, and arrangement of parts, which will be hereinafter fully describedand claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a plan view of a five-horse draftequalizer embodying my invention. Fig. 2 is a cross-section on the line 2 2 in Fig. 1, and Fig. 3 is a similar crosslsection on the line 3 3 in Fig. 1.

5 designates the primary' lever member.

6 is the secondary lever member.

7 and 8 are the doubletrees, and 9 is the singletree.

The primary lever member is fulcrumed at such a point between its ends as to provide arms of unequal length, and this fulcrum is aiforded by a bolt 10, (indicated in Figs. 1 and 2,) said bolt lpassing through the arms of a divided coupling 11, the latter being adapted to embrace the rear portion of said lever member 5. This coupling is formed at its rear with an eye 12 to receive the link 13, attached in the usual Way to an ordinary plow-clevis 14. (See Fig. 1.)

The secondary lever member 6 is arranged in a horizontal position upon the primary lever member 5, and said lever member 6 is fulcrumed near the extremity of the short arm of the lever member 5 by means of a fulcrum-boltvl. (Indicated in Figs. 1 and 3.) The lever member 6 is connected to the lever member 5 and is maintained in spaced relation thereto by the coupler 16, the same having arms 17 18, adapted to it beneath and over the lever members 5 and 6, respectively, as shown by Fig. 3. This coupler is furthermore provided with an intermediate spacing element or plate 19, the same being interposed between the lever members 5 6, said element or plate serving to keep the lever member 6 from riding against or in frictional engagement with the lever member 5 at the point where the former is mounted upon the latter. The long arm of the lever member 6 is arranged to extend or lap over the fulcrumbolt 10 and the coupling-link 11, and to prevent said arm of the lever member 6 from strikingagainst the bolt or the coupling I have provided a spacing-plate 20, which is secured upon the lever member 5 at a point near the coupling and is adapted to engage With the under side of the lever member 6. This spacing-plate serves to hold said lever member 6 in a raised position, and it is free to play over the coupling 11 and the bolt 10.

The doubletree 7 is connected at its middle to the short arm of the secondary lever member 6 by means of the links 21, and this doubletree 7 is equipped with two whifietrees 22 23, which are attached to the doubletrees by the links 24 25, respectively, the points of at tachment of the whiffletrees 22 23 being on opposite sides of the link connections 21 ofl the doubletree 7 to the short arm of the secondary lever member 6. The other doubletree 8 isconnected to the long arm of the primary lever member 5 by means of the links 26, and this doubletree 8 carries another pair of whiliietrees 27 28, which are attached by the links 29 30, respectively, to the end portions of the doubletree8 and on opposite sides of the draft connection 26 between the doubletree 8 and said long arm of the lever member 5.

The singletree 9 isdi'sposedvin" a middle position between the doubletrees 7 8 and the adjacent whiflletrees 23 27, which are supported on the inner end portions of said doubletrees. This singletree 9 is connected by the long links 31 to the long arm of the secondary lever member 6, and thus said lever member 6 has a dou- IOO bletree 7 connected to the short arm thereof, while the singletree 9 is attached to the long arm of the same lever member 6.

In using my equalizer on a `gang-plow the middle horse, attached to the singletree 9, is adapted to Walk in the furrow, While the two teams of horses hitched to the whifletrees 22 and 23 on the doubletrees 7 8 are adapted to walk in the stubble.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A draft-equalizer comprising a primary lever member having long.r and short arms, a doubletree connected to the long arm of the primary lever member and having the spaced singletrees, a secondary lever member fulcrumed directly to and supported by the short arm of the primary lever member and having' a short arm extending beyond the latter and a long arm extending to the fulcrnm of said primary lever member, another doubletree connected to the short arm of the secondary lever member and also provided with spaced singletrees, and a singletree attached to the long arm of the secondary lever member and disposed between the two doubletrees.

2. A draft-equalizer, comprising a primary lever member, a coupling having a fulcrumbolt tted to said lever member to form long and short arms, a secondary lever member fulcrumed by a bolt on the short arm of the primary lever member, doubletrees attached respectively to the short arm of the secondary lever member and the long arm of theprimary lever member, and a singletree connected to the short arm of the secondary lever member, said singletree being disposed between the two doubletrees.

3. A draft-equalizer, comprising a primary lever member, a secondary lever member, a coupler having a spacing element disposed between the two lever members, a coupling attached to the primary lever member and disposed below one end of the secondary lever member, a spacing-plate interposed between the two lever members, doubletrees attached to the arms of the lever members, and a singletree connected to one arm of the secondary lever member.

In testimony whereof I have signed my name to this specification in the presence of two subscribiu g Witnesses.
